Definitions

  • This disclosure relates to the field of communications technologies, and in particular, to a method for detecting link failure of a sidelink and a terminal.
  • a sidelink also referred to as a side link, a sidelink, a sidelink, or the like, is used for direct transmission between terminals without using a network device.
  • a terminal sends sidelink control information (Sidelink Control Information, SCI) over a physical sidelink control channel (Physical Sidelink Control Channel, PSCCH), to schedule transmission of a physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH) for data transmission.
  • Sidelink transmission is based on broadcast, and a receive end terminal does not give feedback on whether reception is successful to a transmit end terminal.
  • Sidelink transmission supports two resource allocation modes.
  • One is scheduled resource allocation (Scheduled resource allocation), in which mode a network device controls and allocates resources for all terminals, and the other is autonomous resource selection (autonomous resource selection), in which mode terminals select resources autonomously.
  • the network device configures a sidelink discovery or transmission resource pool for the terminal.
  • the resource pool includes resource information and related transmission parameters for use in a sidelink discovery or transmission process, for example, an offset value of the first subframe of the resource pool, a bitmap (bitmap) corresponding to the resource pool, whether a PSCCH and a PSSCH are to be transmitted in adjacent resource blocks (Resource Block, RB), a quantity of subchannels, a size of each subchannel, a smallest RB index corresponding to a subchannel, a smallest RB index corresponding to a PSCCH pool (pool), a sidelink received signal strength indicator (Sidelink Received Signal Strength Indicator, S-RSSI) threshold measured by using a channel busy rate (Channel Busy Rate, CBR), and an area identity.
  • S-RSSI Sidelink received signal strength indicator
  • sidelink transmission includes unicast, multicast (or referred to as multicast), and broadcast.
  • a sidelink transmission mechanism neither a receive end terminal nor a transmit end terminal can determine a link state of a sidelink. When the sidelink fails, the receive end terminal and the transmit end terminal continue transmission attempts because they are unable to know that the link has failed. This not only affects transmission performance, but also causes unnecessary waste of resources.
  • Embodiments of this disclosure provide a method for detecting link failure of a sidelink and a terminal to resolve poor transmission performance of a sidelink transmission mechanism caused by the inability of a receive end terminal and a transmit end terminal to determine a link state of a sidelink.

  • a link connection status of a sidelink in sidelink transmission that is, whether link failure occurs on the sidelink, can be determined, to avoid that communication parties still continue attempting to perform communication in a case of link failure, thereby improving sidelink transmission performance and reducing radio resources.
  • a carrier or a resource pool of the sidelink can be updated to restore link quality of the sidelink and improve transmission performance.
